Abstract :
A low cost, programmable, galvanically isolated bipolar eight channel stimulator for patterned electrical stimulator has been developed. The design is based on a newly developed concept. A TMS320C31 DSP-based stimulator is used to generate a wide range of either arbitrary current waves or biphasic current pulses. The DSP-based stimulator can process the stimulated electromyographic (EMG) signal simultaneously. A user-friendly interface for programming of the stimulator has been developed for the host computer, using Windows environment and a push-button control for functional application of the system
